SleepMaker: White Noise & Sleep Sounds Fall asleep faster with white noise, pink noise, brown noise, rain sounds, ocean waves, and a rich library of calming sleep sounds. Whether you need to block distractions, soothe a baby, focus at work, or simply relax before bed, SleepMaker gives you studio-quality audio tuned for deep sleep, stress relief, and natural relaxation. NEW: REAL-TIME NOISE MACHINE White, pink, brown, blue, grey, and violet noise synthesised on-device in real time — not looped recordings, so they never repeat and never fade out mid-sound. Adjust tilt (brighter or darker), stereo width, and volume to dial in exactly the sound that helps you fall asleep. Includes its own sleep timer with fade-out. FULL SOUND LIBRARY • White noise, pink noise, brown noise — procedural, loop-free • Rain sounds, thunder, storms, rainfall on tents • Ocean waves, streams, rivers, waterfalls • Forest ambience, crickets, birds, wind • Fan sounds, hairdryer, vacuum, airplane cabin, air conditioner • Baby-specific: womb, heartbeat, lullabies, swaddle ambient • Focus loops for study, work, meditation, and yoga CUSTOM MIX BUILDER Layer any sounds together and save your personal mix. Combine rain, fan, and distant thunder — or ocean, seagulls, and wind. Mix to your taste and recall it with one tap. SLEEP TIMER WITH FADE-OUT Set the timer and drift off. SleepMaker gently fades the audio to zero over your chosen duration so it never stops abruptly and never wakes you up.
